lete. Capsule with a large central placenta, bearing many seeds, 
which are very minute, without albumen. — Small herbaceous 
marsh plants, with leaves all radical and undivided; or aquatic 
plants, with compound root-like leaves bearing bladders. 
1. Tinguicula. Calyx 2-lipped, upper lip 3-lobed. 
2. Utiucui.aria. Calyx bipartite, upper segment entire. 
1. Pinguxccla Linn. Butterwort. 
Cal. 2-lipped, lower lip bifid, upper of 3 segments. Cor. 
ringent. Stigma sessile. Capsule with 2 valves at the top. — 
Named from pinguis, fat; the leaves being thick and greasy to 
the touch. 
1. P. vulgaris L. ( common B.); spur subulate cylindrical 
nearly straight shorter than the veinless limb of the corolla 
whose segments are very unequal oblong-obovate rounded even 
diverging from each other and all entire, capsule ovate acute. 
E. B. t. 70. 
Bogs, moist banks and heaths, most abundant in the North, y . 
5 — 7. — Foliage radical, covered with minute raised crystalline points, 
fleshy, the margins involute. Scapes single-flowered, and the calyx 
somewhat downy. Flowers purple, very handsome, drooping ; palate 
covered with white compactly jointed hairs. Anthers vertical, placed 
just beneath the large horizontal plate or lobe of the stigma. Caps. 
ovate, 1-celled, bursting half-way into 2 valves. — The leaves are said 
to coagulate milk, whence the English name. 
2. P. grandiflora Lam. (large-flowered B.) ; spur subulate 
cylindrical often notched about as long as the veined limb of 
the corolla whose segments are very unequal broadly-obovate 
wavy contiguous or overlapping at the edges, the middle one of 
the lower lip notched, capsule ovate obtuse. E. B. t. 2184. 
Western part of the county of Cork, in marshy ground ; and at 
Kemnare. If. 5,6. — This beautiful plant, apparently as rare upon 
the continent as in Britain, may he easily cultivated for a succession 
of years ; like P. vulgaris, its old leaves die away in winter, and buds 
or hybernacula are formed, which expand into perfect individuals in 
in the spring. This is probably only a variety of the last ; Mr. Ben- 
tham indeed unites them : dried specimens are frequently doubtful. 
3. P. alpina L. ( alpine B.) ; spur conical shorter than the 
unequal limb of the corolla, and curved towards the lower 
retuse lip, scape glabrous, capsule acute. E. B. S. t. 2747. 
Bogs in Scotland, very rare. Isle of Skye ; Black Isle, Ross- 
shire. If-. 6. — Leaves and flowers about the size of P. Lusitanica ; 
but the texture of the foliage most resembles that of P. vulgaris. 
Corolla yellowish ; within on the under side is a tuft of deep-yellow 
crystalline hairs. Spur remarkably short and conical, curved upwards.
